Preparation method for edge-functionalized graphite via mechanic-chemical process using low grade graphite and the graphine nano-plate manufactured thereby

摘要

The present invention relates to a method for producing graphite functionalized with edges having a high hetero atom doping rate while using low-purity graphite, a method for preparing a graphene nano plate, and a graphene nano plate prepared therefrom, and the manufacturing process It is very simple, economical, and can be mass-produced, and it is possible to use low-grade graphite with a large average particle size and a low carbon element content in the raw material, thereby enhancing economic efficiency. Rather than using conventional finely pulverized graphite, doping of heteroatoms significantly The high-ratio edge makes it possible to manufacture functionalized graphene nanoplates.
